Trait Implementations

impl<'tcx> Clone for DropckOutlives<'tcx>

pub fn clone(&self) -> DropckOutlives<'tcx>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Copy for DropckOutlives<'tcx>

impl<'tcx> Debug for DropckOutlives<'tcx>

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for DropckOutlives<'tcx>

pub fn hash_stable(
    &self,
    __hcx: &mut StableHashingContext<'__ctx>,
    __hasher: &mut StableHasher
)

impl<'tcx, '__lifted> Lift<'__lifted> for DropckOutlives<'tcx>

type Lifted = DropckOutlives<'__lifted>

pub fn lift_to_tcx(
    self,
    __tcx: TyCtxt<'__lifted>
) -> Option<DropckOutlives<'__lifted>>

impl<'tcx> QueryTypeOp<'tcx> for DropckOutlives<'tcx>

type QueryResponse = DropckOutlivesResult<'tcx>

pub fn try_fast_path(
    tcx: TyCtxt<'tcx>,
    key: &ParamEnvAnd<'tcx, Self>
) -> Option<Self::QueryResponse>

Give query the option for a simple fast path that never actually hits the tcx cache lookup etc. Return Some(r) with a final result or None to do the full path.

pub fn perform_query(
    tcx: TyCtxt<'tcx>,
    canonicalized: Canonicalized<'tcx, ParamEnvAnd<'tcx, Self>>
) -> Fallible<CanonicalizedQueryResponse<'tcx, Self::QueryResponse>>

Performs the actual query with the canonicalized key -- the real work happens here. This method is not given an infcx because it shouldn't need one -- and if it had access to one, it might do things like invoke sub_regions, which would be bad, because it would create subregion relationships that are not captured in the return value.

pub fn fully_perform_into(
    query_key: ParamEnvAnd<'tcx, Self>,
    infcx: &InferCtxt<'_, 'tcx>,
    output_query_region_constraints: &mut QueryRegionConstraints<'tcx>
) -> Fallible<Self::QueryResponse>

impl<'tcx> TypeFoldable<'tcx> for DropckOutlives<'tcx>

pub fn super_fold_with<__F: TypeFolder<'tcx>>(self, __folder: &mut __F) -> Self

pub fn super_visit_with<__F: TypeVisitor<'tcx>>(
    &self,
    __folder: &mut __F
) -> ControlFlow<__F::BreakTy>

pub fn fold_with<F>(self, folder: &mut F) -> Self where
    F: TypeFolder<'tcx>, 

pub fn visit_with<V>(
    &self,
    visitor: &mut V
) -> ControlFlow<<V as TypeVisitor<'tcx>>::BreakTy, ()> where
    V: TypeVisitor<'tcx>, 

pub fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool

Returns true if self has any late-bound regions that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound regions that appear free.

pub fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool

Returns true if this self has any regions that escape binder (and hence are not bound by it).

pub fn needs_infer(&self) -> bool

pub fn has_placeholders(&self) -> bool

pub fn needs_subst(&self) -> bool

pub fn has_free_regions(&self) -> bool

"Free" regions in this context means that it has any region that is not (a) erased or (b) late-bound.

pub fn has_erased_regions(&self) -> bool

pub fn has_erasable_regions(&self) -> bool

True if there are any un-erased free regions.

pub fn is_global(&self) -> bool

Indicates whether this value references only 'global' generic parameters that are the same regardless of what fn we are in. This is used for caching.

pub fn has_late_bound_regions(&self) -> bool

True if there are any late-bound regions

pub fn still_further_specializable(&self) -> bool

Indicates whether this value still has parameters/placeholders/inference variables which could be replaced later, in a way that would change the results of impl specialization.
